Specification of Letters Patent.

Patented Nov. 30, 1915.

Application filed March9, 1915. Serial No. 13,138.

To all whom it may concern y 1? -e it known that I, ERNEST RICHARDSON, a citizen of the United States, residing at College Hill, in the county of Beaver and State of Pennsylvania, have invented new and useful Improvements in Tables, of

which the following is a specification.

My invention relates to tables or similar articles having porcelain enameled metal tops. 1

It is one of the objects of this invention to construct the sheet metal for table tops,

kitchen cabinet tops, and the like so that they will not warp or buckle in the enamel burning furnace or during their cooling after having been removed therefrom.

Another object is to manufacture the said tops with enameled border flangesso that the enamel on the flanges will not be cracked or broken by reason of blows thereon re ceived during the shipment of the tops or during their subsequent use. My table tops are extensively used in restaurants in which the tables are pushed about carelessly, particularly while the fioors are being cleaned, whereby the corners ofsome of the tables strike the flanged sides of other tables and crack or break the enamel thereon when the enamel is applied to the flanges in the usual manner or in the same manner in which it is applied to the upper surface of the tops.

Another object is to provide the enamel 0n the said flanges with a color coat'applied in flecks or small spots in order to prevent the color coat from chipping off or cracking as a color coat is liable to do when it receives hard blows or extreme changes in temperature. l

A still further object ofmy invention is to secure the said tops to a table cabinet or other body or support in a convenient and cheap manner. 7 Referring tothe accompanying drawings, Figure 1 isaperspective of a table embodying the principles of my invention, the lower portionslofthe legs being broken away; Fig. '2 is 1a.: section of Fig. 1 on the line 11-11; and Fig. 3 is a bottomplan view of the table one side being broken leave .a narrow border 4 extending entirely- ,extreme changes of temperature.

' around the top 1. This border is comparatively narrow and serves, with the flange 5 depending from the edges of the top 1,. to stiffen the metal so that it will notwarp or ing after it has been taken therefrom. was. found that the Said flange alone would not prevent the metal from warping or twlsting out of shape, but that by depressing the metal from near the edges of the top 1 the latter would remain in its normal flat condition during and after its treatment in the said furnace.

After the sheet metal 2 has been given the depression 3 and theborder 4 and provided with the border flange 5, I coat tlie'top with the coat 6 of enamel which I have shown on the upper side of the top and on the outer buckle during the time the topfis in the enamel burning furnace or while itis coolface of the flange 5, though it may cover the when subjected to hard blows, or rapid or The coated metal top is. subjected to the action of a suitable enamel burning furnace in which the enamel is fused on the metal. After the coated metal has been taken from the fur nace and allowed to cool, the coat 6 is covered with the color coat'of enamel, which is spread in an even layer 7 over the upper surface of the top but is applied in flecks or spots 8 of small area on the coat 6 on the flange 5. It has been found'that the flecks 8 will not chip, off or crack when subjected to very hard blows or tosudden or extreme changes of' temperature. The coloring material-in the second coat renders it somewhat brittle, and requires it to be consider ably thicker than uncolo'red coats are required to be. Consequently, the first, -or ground, coat 6 being without color (or at least .having a very little coloring matter) may be very thin, and the second coat, containing color may be thick on the flange 5 provided it be in spots or flecks of small area. The spotsor flecks can freely expand edgewise without danger of their breaking or cracking, and thesmallness of the spots or flecks prevent their chipping or cracking,

this result being secured in part at least by.

posite strips 9 with the endsof the former" abutting against the inner faces of the said strips 9. Screws 12 extend through the flange 5 into the ends of the wooden strips and secure the top 1 to the wooden strips. The metal strips 9 have lugs or ears 13 bent at right angles thereto, on which the said Wooden strips 11 rest. The ears 13 and the 'strips 11 are secured together by the bolts 14- and nuts 15.

This application is a continuation in part of my application Serial "Number 829,002, filed April 2, 1914. I

I claim 1. In a table orthe like, a sheet-metal top having a depending flange on the edges thereof, a coat of enamel on the upper surface of the top, the said enamel containing enamel containingsaid coloring matter on the said enamel on the flange.

2. In a table or the like, a sheet-metal top having a depending flange on the edges thereof, a coat of enamel on the exterior surface of the flange, the said coat being so thin as to prevent its breaking or cracking when subjected to severe blows, and flecks of enamel containing coloring matter on the said thin enamel.

In a table or the like, a sheet-metal top having a depending flange on the edges thereof. a coat of enamel on the exterior surface of the flange. and flecks of enamel containing coloring matter on the said enamel.

Signel at Beaver Falls. this 4th day of 'March, A. D. 1915.
